Linear Power Supply vs SMPS

I bought one listed from a certain auction site listed as ‘Upgraded 120W Hi-End Audio PSU DC19V@4.5A Ultra Low Noise Linear Power Supply’. Chinese origin but internal pics shown. I’ve had it around 12 months with no issues, it is well built. Definitely improved the SQ.

I did try the Farad on its own but after a week I just wanted to go back to the excitement and involvement the standard SMPS was giving me. I have to say breathed a slight sigh of relief when it went back in!

I’ve also tried piggy backing a couple of switches but I’ve found this tended to sound a bit over damped, so not gone any further down that hole!

As I’ve said the system sounds inherently ‘right’ at the moment, so I’m tempted to leave well alone and just enjoy what it does. It certainly gets me very close to how I think I hear a real live performance!

Hi :slightly_smiling_face:

Look for Stack Audio,.many people think their Volt LPS is really good.
And it costs reasonable money if you want to try it.

They have made it with different specifications for volts and amperes.
Send Theo (as is the owner’s name) an email and ask if they have someone that fits your Asus.
I myself have this Volt LPS and think it is good where it “serves” :wink:.

Your second question,.for you to get a 100 percent answer,.ask that question to @Simon-in-Suffolk or @ChrisSU .
But I think Simon has recommended Cisco here,.but I can’t remember which model number.

Sbooster seem to have 19V alternative

Fair enough. Happy days that you have found the config best for your tastes :+1:

Aha,.you are also from Sweden,.cool :smiley:

Yupp, 1000km south of you :slight_smile:

you only should typically have ONE router on your home network - and that is typically the device that connects your home network to the internet. Wifi and switches are not routers - but they can be attached to routers either via Ethernet or directly - Indeed many broadband routers have four switch ports attached and a wifi controller and access point attached.

As far as switches - it depends on your home layout - a broadband router device with its inbuilt switch ports may be ideal - or depending on layout a separate switch connected to the router’s switch ports might be preferable to reduce the number of cables.

I advocate using a wifi solution and switches that support IGMP snooping - this is a method that optimises and minimises sending special data called multicast data to devices that don’t want it - thereby reducing processing noise and overhead in devices like streamers. All very low level and marginal - but you know what audiophiles can be like.

Legacy catalyst switches like the Cisco 2960 are cheap used and are very capable as default in this regard.

Mike,
What u really need is a ND555😉
Really makes big difference

Sorry to interrupt point of thread

Indeed, fortunately I have a nice new one, 3 weeks into burn-in and it’s a complete delight.

Thought u had ndx2/555ps
The nd555 sure is an upgrade over the above combo
Enjoy!

Fidelizer makes a nice product that will be customized to the requested voltage. For a bit more they can add a second tap.

I’m using for router and network switch.

MCRU have a huge list of power supplies for network appliances and so forth and asking for a custom supply doesn’t cost any more than getting one off the list.

I got them to do two non standard LPS for a turntable and a streamer not on their list both for Japanese 100v instead of UK 240v. Didn’t cost a penny more.

I wouldn’t take anything Linn does an an endorsement. They are clueless about virtually every aspect of audio design, including tonearms and their own turntable - which they have failed to understand even after 50 years and are just making worse. Which is what you’d expect from a company that started out as a machine shop. I’m actually doing some work on transformers at this very moment, though I haven’t completely thought through what’s going on in SMPSes quite yet. My present position (or suspicion) which may change, is that there isn’t enough magnetising inductance in their transformers to deliver current at low frequencies - and if they can’t deliver it, it doesn’t come out of the amplifier and go through the speakers. This may not matter in systems with limited LF output or very low power draw but it’s nonetheless a potential limitation. The fact they have built-in regulation may be an advantage - probably is - but not all regulator design is equal and the standard SMPS industry practices are not encouraging (TL431s everywhere as Vrefs for example - not that it’s not a great part in other use cases). There is also an inherent conflict of purpose in the standard practice of having the output capacitors also be the reservoir capacitors. And don’t expect Linn to be able to give you answers to any of these questions, they have been horrific with power supplies ever since the Valhalla - which I still believe should have failed British Standards of the time.

Thank you for your reply, very insightful. I am now reading your earlier posts again lots of insights.

Odd then that said turntable has been hugely successful and is very highly regarded, still selling after many decades of production. Guess all the happy owners don’t realise what a piece of junk they’ve bought.

@Christian_Thomas thank you - what I have noticed is the the Linn Klimax streamer (with SMPS) sounds very clear and precise and a lot of that is SMPS I suspect, my LP12 got worse with a Radikal vs Armaggedon, again no real heft to the bass, (I also have a a Phonosophie P3 with Naim arm and PS), I have heard the Linn Klimax amps and speakers, to my ears they sound lightweight. Maybe it is the SMPS I don’t know. It seems the Linn house sound is rhythmical clean and clear but lacking decent weight (to my ears anyway)

I guess that comment must apply to other companies as well, the first one that comes to mind is SME. How many businesses started out on the kitchen table, in a garage?

Was that post some sort of plant, maybe a PhD in psychology trigger question. In which case we should have been consented.
